Question

Part 1

Zinc chloride (ZnCl2) is 52.02% chlorine by mass. What mass of chlorine is contained in 83.0 g of ZnCl2? Answer in units of g.

(part 2 of 2)

How many moles of Cl is this?

Answer in units of mol.

Answer 1

Part 1

52.02 % of 83 = 0.5202 x 83 = 43.1766 g

Part 2

atomid mass of Cl is 35.453 g

so 1 mole has mass 35.453 g

so (43.1766 / 35.433) = 1.218542037 moles
